ENERAL DESCRIPTION
Your boat is equipped with a 12 V DC electrical system, powered by a battery. The
battery is kept charged by the alternator of the engine. The battery voltage is indicated
by the engine instrument (optionally by a depth finder/plotter).
All cabling is done using pre-manufactured cable harnesses, adopted specifically for this
boat model. All cable ends and consumers (e.g. bilge pump, winches, and lights) are
coded and can be identified on the attached schematics.
All consumers are connected through circuit breakers to the battery. The breakers are
of automatic type and can easily be reset when the cause of the problem has been
identified. All are also individually marked on the boat for easy trouble-shooting.
The complete system is controlled by the main battery switch, installed on the battery
box, and which can cut the power to all consumers with exception of the bilge pump.
The bilge pump has a permanent power supply, to function at all times.
When leaving the boat for longer periods, always turn the main battery switch(es) to
OFF to avoid battery drain caused by accidental activation of the remote switches.
Ockelbo has equipped the boat with an empty spare circuit where Auxiliary Equipment
(aftermarket products) can be installed. It is marked as EXTRA on the fuse panel.
Any modifications to the electrical system must be made by experienced staff. Using the
hull as one pole (positive or negative, for instance for earthing of consumers) will likely
cause major issues including risk of corrosion damages to the hull and must be avoided
at all times. Batteries can generate high currents that can be fatal and cause sparks and
fires. Make sure you always understand how the system works before you do any
maintenance or modifications, such as disconnecting batteries, adding AUX equipment or
repair work.
WARNING
Always disconnect the power using the main battery switch, before any work on the electrical
system. Failure to do so may cause electric shocks, or sparks that can ignite fuel fumes.
Always ventilate areas with fuel or batteries before any work, and never use open flames in
these areas.
CAUTION
When leaving the boat for longer periods, always turn the main battery switch off to avoid
accidental battery drain. Failure to do so may hinder the bilge pump from working, potentially
causing the boat to sink in case water leaks into the bilge. Never leave the boat unattended
for lengthy periods, and check battery charge level regularly.
